 Description QCD makes the most challenging component of the Standard Theory of Particle Physics. It is a strong interaction, yet quarks are asymptotically free. It is unique in harboring the emergent phenomena of dynamical mass generation and confinement of colored excitations. It is also astonishingly peculiar in that the fundamental degrees of freedom which enter the Lagrangian are not accessible in the detectors. We cannot see quarks and gluons, yet they conspire to outpour a plethora of hadrons and account for most mass observed in the visible universe, outshining the Higgs mechanism almost completely. Can we aspire to explain the observable world of hadrons, their static and dynamic properties, starting from the QCD Lagrangian? The current status is that the detailed understanding of even the simplest of strongly interacting bound states has been non-trivially elusive to us. In this talk, I shall highlight some of the headway we have made in this direction within the formalism of its fundamental field theoretic equations of motion. Support Email: epeinado@fisica.unam.mx
